Just like the Oscars, Green Car Journal decided a few years ago to up the number of nominees for its annual award. For the annual "Green Car of the Year" award, given out at the Los Angeles Auto Show each year, there are five finalists. For the "Green Car Technology" award, there are a fantastic ten. At the 2014 Washington Auto Show today, the Cadillac ELR and its regen on demand brakes managed to beat out the nine other finalists to claim the second annual "Green Car Technology" award.

What is the purpose of the "Green Car Technology" award? Green Car Journal says it wants to reward "technologies that enable significantly improved environmental performance in vehicles today," which is why only fuel-saving technologies that were "in use on American highways during the award year" can be considered.

The Caddy's brakes beat out the Acura Sport Hybrid SH-AWD powertrain, the Audi 3.0-liter turbodiesel engine, the BMW carbon-fiber passenger shell from the i3, the 1.0-liter EcoBoost engine used by Ford, the plug-in hybrid powertrain in the Honda Accord, Hyundai's hydrogen fuel cell technology, the regenerative brakes in the Mazda i-ELOOP, the plug-in hybrid powertrain used in some Porsche models and, finally, the Ram 3.0-Liter EcoDiesel engine.

Last year, Green Car Journal gave Mazda's Skyactiv technology the inaugural Green Car Technology award.

Cadillac ELR Regen On Demand Wins 2014 Green Car Technology Award
Green Car Journal Lauds Cadillac's Electric Car Tech at Washington Auto Show


WASHINGTON, Jan. 22, 2014 /PRNewswire/ -- Cadillac's innovative Regen on Demand technology has taken top honors as the winner of Green Car Journal's 2014 Green Car Technology Award™. The prestigious award was presented at a Green Car Journal press conference during the Washington Auto Show's second Policy Day.

"Cadillac has cleverly evolved a common electric-drive efficiency system into an intriguing feature that adds a new dimension to the driving experience," said Ron Cogan, editor and publisher of Green Car Journal and CarsOfChange.com. "Ever-increasing efficiency is crucial to our driving future, yet efficiency itself is not an attraction for a great many car buyers. Cadillac's Regen on Demand is an inspired example of how technology can increase efficiency while connecting with a driver, enhancing driving dynamics along the way."

Like most regenerative braking systems in hybrid and electric vehicles, the ELR's electric motor acts as a generator while braking, automatically recovering energy that's delivered to the batteries as electricity. Unique to the ELR extended range electric vehicle, Regen on Demand also allows a driver to instantaneously engage and disengage regen at will by pulling back or releasing left or right steering wheel paddles. This not only creates electricity on demand, but enhances driving dynamics by inducing regen drag that allows decelerating before turns and in other circumstances, without braking or requiring a driver's foot to reposition from the accelerator pedal.

"Regen on Demand is one of the key systems enabling the Cadillac ELR to merge performance with efficiency in a dynamic new way," said Jim Vurpillat, director of emerging markets at Cadillac. "Putting regenerative braking at the driver's fingertips supports the ELR's 340-mile total driving range while also adding a fun-to-drive element matching the engaging design and performance of this premium luxury coupe."

Along with Cadillac ELR's Regen on Demand, 2014 Green Car Technology Award™ nominees include the Acura Sport Hybrid SH-AWD powertrain; Audi 3.0-liter TDI clean diesel engine; BMW i3 carbon fiber reinforced plastic passenger cell; Ford 1.0-liter EcoBoost engine; Honda Accord plug-in powertrain; Hyundai hydrogen fuel cell; Mazda i-ELOOP brake energy regeneration system; Porsche plug-in hybrid powertrain; and Ram Truck 3.0-liter EcoDiesel engine. Each of these finalists earns Green Car Journal's 2014 Product of Excellence honor that acknowledges the important role they play in creating a new generation of highly efficient vehicles.

The Green Car Technology Award™ focuses on enabling technologies that bring significantly improved environmental performance to today's production vehicles. Technologies must be in use on American highways during the award year to qualify for consideration in the Green Car Technology Award™ program.

      I disagree about high regen being bad for range/efficiency. When used in stop-and-go traffic (and careful accelerator pedal use), I easily get 50% more range than if I just used coasting and braking. Of course, your mileage may vary, but I can get 85 miles per charge in the city on my i-MiEV, and that's without hypermiling it.

        You mean it does the same thing as slowing down in a normal hybrid/EV. Why add an extra switch and require the driver to know when to pull it. I want to use the speed control (the accelerator pedal) to do just that - control speed. If that requires regen, great. Next thing is they will put in a manual switch for stability control. If you sense you have lost control, just push the button located on the dash to activate ESP - no sense in letting computer figure that out. Such a joke its not even funny.

        Well Accord Hybrid can do the same with the B setting. It's not paddle shifter but not big difference really. Certainly more logical setting.

      Which is also stupid. The friction brakes should have nothing to do with regen. The blending method has never worked well, its always jerky or laggy. Full regen should be accessible by the speed control (accel pedal) BEFORE the friction brakes need to be applied. Thats the way Tesla does it. One pedal driving and they are praised all the time for it.

      No friggin way. It's not new tech at all, and not as game changer than the CFRP cell from BMW or even the 1.0 liter engine from Ford (not because it's small but because it's meant to be installed on cars as large as the Fusion/Mondeo in European markets). The only other candidate quoted not worth to the prize was the 3.0 TDI from Audi as that kind of engine (not as refined, but again, not new tech at all) has been around in Europe for years, same for the Ram engine. Good diesels, but in Europe that's like 60% of the market!

        Yes, I think you summarize it very well by saying it's not a game changer. If BMW brings that CF production tech to the larger market, ... wow.

        Direct injection isn't anything new either. But Mazda won for Skyactiv last year. Apparently, this award isn't about "new" technology. Hard to say exactly what it's for.

          Skyactiv is more than DI. Its definitely a lot more than 20 year old regen technology.

      To those who have commented about the award being "just" for regenerative brakes ... it is MORE than that !!! Yes, regenerative brakes have been around for years and years ... Cadillac has added paddles to the steering wheels (like paddle shifters on the old gasoline cars) except these paddles engage the regenerative brakes ... so YOU can apply them when you need to slow down a bit, enter a corner or when coasting. It is a great idea, if you think about it and consider the fact that the superior continuously variable electric transmission in the ELR means you would - otherwise - have no need for paddles to shift. Also, if you use these right, you could probably go 100,000 on the original brakes !!! I wish my car had them !!!

      Regen is variable and can be programmed in the controller to act in a variety of ways. Chevrolet designed it to be constantly engaged at a 0% throttle level in motion on the car to emulate the drag of the gasoline engine, but when you step on the brakes, it steps up the regen level dramatically. So there is a difference between coasting regen and braking regen.

      These guys are douchebags. Patting each other on the back about what a great job they did ripping off Club Car technology. Golf carts have been around 20+ years.. They need to award NEW technology. Hydrogen maybe???

      For being the Green Car TECHNOLOGY award, weak sauce giving it to the ELR. I mean really, between Mazda's lightweight super capacitors, Hyundai's fuel cells (though admittedly not on the road yet), and Honda's crazy innovative new powertrain, I just named 3 clearly more worthy recipients of the technology award.

        @MistyGreen
        Actually, you are wrong. There are nine others on the list more worthy of this award. Adding an offset to speed request is not ground breaking. We did that 20 years ago testing cold start on common rail Cummins diesels on gen sets.Same concept.

        Yeah, the i-Eloop system is way more innovative.

      Yes, that's called coast braking, and i agree that it is a poor design decision for it to even exist in the first place.

      That smirk says "ha ha fooled you, suckers!" Really? It's 2014 and the best green car technology is one which has been in the US market since we got the Prius??? What about bringing a viable process for making passenger cars out of carbon fiber, a much less energy intensive material than aluminum OR steel, to a consumer production level? I mean a lighter car saves you energy by not using it in the first place. I do not like... Seems like winning by doing the least possible to satisfy your marketing department...

      What's non-coasting regen? Regen decelerates the car, period.
